It took 8 months, 150 tests and over 1,000 total working hours to reclaim what is rightfully mine :)

Let's give Fletcher one final surprise and go subscribe to his channel. At this moment he has 2 subs and I'm one of them.    / @fletcherrollinson9905  

I started a company called CrunchLabs where we build a toy together and then I teach you all the juicy physics for how it works. So if you want to learn to think like an engineer and have really fun time doing it, check out the current promotion where you get 2 FREE boxes at crunchlabs.com

You should also go subscribe to the CrunchLabs YouTube channel cause we’ve got some bangers in the pipeline- youtube.com/crunchlabs

  • This is an incredible video! Thank you mark for everything you have done for me! I am truly so grateful. That was some of the most fun I’ve ever had!

    The DEDICATION for his fan is unbeatable. Got my respect.

    Just seeing this three years on. Praying that Fletcher is still in remission and living a normal life. This was truly wonderful and inspiring. What an incredible gift for a kid, and family, that have been through a lot. Not sure that you know the impact such things can have on a person undergoing serious medical treatment. Your video call prior to chemo could have literally made the difference between success and failure. Thank you so much. Faith in humanity partially restored.

    O MANUAL DO MUNDO 🥰🥰❤❤
  • This is one of the best videos on YouTube. First, I'm overwhelmingly happy to see Fletcher doing better and in high spirits. Second, I'm 36 and wish I had a party like that. What a great way to take someone you love and are passionate about to turn it into something special for not only Fletcher and his family but myself also. I was extremely depressed from my father's passing and a recent divorce and I literally smiled through this video. I even got out of bed and ate something and plan on getting out of the house today. You are truly special and I'm happy to see everyone enjoying themselves. Plus, that's the coolest way I've ever seen a Tesla being used. With love. B
  • That's so nice of you to do that to a kid you barely even know. I would have been crying of happiness.

    18:42 the pressure was so immense that even before it exited the top it was coming out of nail holes.
  • @FuzzzyJunior
    You cannot hate Mark. What he did for Fletcher is completely heartwarming.
  • @vinsplayer2634
    Devil's toothpaste looks absolutely unreal. I can't even imagine what it would be like to see it in real life.
  • @MeAMoose
    I think this shows the kind of person Mark is. A true legend.
  • @nichego4482
    Mark you are amazing! you sparked creativity around everyone watching your videos you inspire alot of people each video.
  • @BlackGryph0n
    The absolute BEST part of this video isn't any of the experiments. It's the pure, selfless humanity of everyone involved. You don't need to agree with someone to be kind, caring, and compassionate. Thank you for being one of the few who routinely displays that in their content.
